Russia’s central television VGTRK special correspondent Igor Kornelyuk was heavily wounded in the shelling near the eastern Ukrainian city of Luhansk and died at hospital later on Tuesday. The fate of sound engineer Anton Voloshin, who worked with Kornelyuk, is unclear yet.

Kiev’s plans to introduce martial law in Donetsk and Luhansk regions will give a free hand to Ukrainian military forces, Lavrov added.

“I hope for common sense of the Verkhovna Rada,” he noted, adding that "nothing can be ruled out as we witnessed quite many demonstrations of aggressiveness by incumbent Ukrainian rulers.”

Ukraine held gas talks in terms of ultimatums without any negotiating culture, Lavrov noted. “They did not behave like Europeans,” he said.
